Hi Dave,

I agree fully, and Joern will do this. I only meant that we don't want
to submit until any patch has been through regression testing to make
sure it doesn't break anything.

Fully agree - our remit from Atmel is to work completely in the open. Up
until now we've been working on GCC itself, and so those have gone to
the GCC mailing list. You'll see quite a few patches from Joern recently
there. But clearly for AVR LibC we need to work here.

Glad to do our bit. Hope to see the first patches here soon.

Best wishes,
